摘要：OCT is a recently developed optical interferometric technique for non-invasive diagnostic medical imagingin vivo; the most sensitive optical imaging modality.OCT finds its application in ophthalmology, blood flowestimation and cancer diagnosis along with many non biomedical applications. The main advantage ofOCT is its high resolution which is in μm range and depth of penetration in mm range. Unlike othertechniques like X rays and CT scan, OCT does not comprise any x ray source and therefore no radiationsare involved. This research work discusses the basics of spectral domain OCT (SD-OCT), experimentalsetup, data acquisition and signal processing involved in OCT systems. Simulation of OCT involvingmodelling and signal processing, carried out on Lab VIEW platform has been discussed. Using theexperimental setup, some of the non biomedical samples have been scanned. The signal processing andimage processing of the scanned data was carried out in MATLAB and Lab VIEW, some of the results thusobtained have been discussed in the end.
